Association of dissected ascending aorta diameter with preoperative adverse events in patients with acute type A aortic dissection.

BACKGROUND: Acute type A aortic dissection (ATAAD) is a life-threatening disease associated with high morbidity and mortality. AIM: To evaluate the diameter of dissected ascending aorta in patients diagnosed with ATAAD and whether the aortic diameter is associated with preoperative adverse events. METHODS: A total of 108 patients diagnosed with ATAAD who underwent emergency operation under hypothermic circulatory arrest were enrolled in this study. Demographic characteristics and perioperative data were recorded. In all patients, preoperative chest and abdomen computed tomography (CT) scans were performed. RESULTS: Median age of the patients was 61.5 (52.5-70.5) years and median body mass index (BMI) was 28.2 (25.1-32.6) cm2. The number of female patients was 37 (25%). Median diameter of the ascending aorta was 5.0 (4.5-6) cm and 53.8% of the patients had an aortic diameter < 5.0 cm, while 32.3% of the patients had an aortic diameter of 4.5cm and 72.0% had an ascending aorta diameter < 5.5 cm. The diameter of the ascending aorta did not differ in patients with vs without preoperative adverse events: Preoperative neurological dysfunction (P = 0.53) and hemodynamic instability (P = 0.43). Median age of patients with preoperative hemodynamic instability was 65 (57.5-74) years, while it was 60 (51-68) years in patients without (P = 0.04). CONCLUSION: Although current guidelines suggest replacing the ascending aorta with a diameter > 5.5 cm, most of the patients with ATAAD had an aortic diameter of less than 5.5 cm. The diameter of the ascending aorta in patients diagnose with ATAAD is not associated with preoperative adverse events.

Diagnostic dilemma in spontaneous innominate artery pathology: a case report.

We report the case of a 71-year-old female who presented with sudden onset of right cervical pain and ipsilateral arm hypoaesthesia. The diagnostic evaluation revealed a pathology of the origin of the innominate artery (IA). The differential diagnosis was among a spontaneous acute dissection and a ruptured pseudoaneurysm. The dilemma of the proper treatment emerged. Surgical or medical treatment? Open or endovascular approach? The patient was offered an open treatment under cardiopulmonary bypass and sort circulatory arrest. As less than ten cases of isolated IA dissection have been previously reported in the literature, we discuss the differential diagnosis difficulties and the treatment options.

Common swelling of the dorsal thoracic wall brings an unexpected finding: elastofibroma dorsi.

Elastofibroma is a rare benign, soft-tissue slow-growing tumor seen predominantly in elderly females. We present such a case in a 46-year-old female. She presented with gradually increasing soft tissue swelling of 8×6 cm in the right inferior subscapular region. MRI showed a large intramuscular lesion with atypia. She underwent excisional biopsy and the histopathology and immunochemistry showed elastofibroma. We present this rare case to emphasize the important role of the diagnostic tools. A definitive diagnosis helps to avoid unnecessary wide and radical resection.
